test case and this too is working on other compilers like programz

My code

#include <iostream>
#include<vector>
using namespace std;
int main() {
	int t;
	cin>>t;
	for(int i=0;i<t;i++)
	{
	    int n;
	    cin>>n;
	    int u=0,k,flag=0;
	    for(int j=0;j<n;j++){
	        cin>>k;
	        if(k<u){
	            cout<<"No \n";
	            flag=1;
	            break;
	        }
	        u=k;
	    }
	    if(flag==0)
	    cout<<"Yes \n";
	}
}

@prernapal135
Have corrected your code.
the thing is when u are getting no as answer u are breaking the loop and ignoring the rest of the inputs .
This thing can mess up the inputs for the test cases afterwards.

#include <iostream>
#include<vector>
using namespace std;
int main() {
	int t;
	cin>>t;
	for(int i=0;i<t;i++)
	{
	    int n;
	    cin>>n;
	    int u=0,k,flag=0;
	    for(int j=0;j<n;j++){
	        cin>>k;
	        if(k<u){
	            //cout<<"No \n";
	            flag=1;
	          //  break;
	        }
	        u=k;
	    }
	    if(flag==0)
	    cout<<"Yes \n";
	    else
	    cout<<"No\n";
	}
}
